Parameter detection device and system for portable subway wheel pairs

Abstract

The invention relates to the technical field of rail engineering and discloses a parameter detection device for portable subway wheel pairs. The device includes an arc-shaped track arranged at a distance from wheel treads and a sliding block arranged on the arc-shaped track, wherein the sliding block can reciprocate along the arc-shaped track and is provided with a line laser light source and a photographing device, a laser plane of the line laser light source is projected on the wheel treads along a specified angle to form light bars, a camera of the photographing device collects a light barimage of the wheel treads along another specified angle, the line laser light source and the photographing device are connected with a processor, the processor is further connected with a touch screen, an image processing module and a data transmission module, the image processing module is used for processing the light bar image collected by the photographing device, parameters of the multiple wheel treads are obtained through calculation, the touch screen is used for displaying the light bar image collected by the photographing device and the multiple parameters obtained through calculationby the image processing module, and the data transmission module is used for performing data transmission between the processor and a server.

Description

technical field [0001] The invention relates to the technical field of track engineering, in particular to a parameter detection device and system for a portable subway wheel set. Background technique [0002] Rail transit has gradually become the backbone of large cities. Wheels are the final stressed parts of vehicles. They transmit the load of vehicles to the rails and rotate on the rails. Therefore, keeping the wheels in good condition is a prerequisite for the safe operation of the subway. The relevant departments of rail vehicles in my country have clear regulations on the wear limits of various types of wheels. When overhauling wheels, the degree of wear of wheels is mainly judged by measuring the geometric parameters of the wheel rim tread profile. In this way, there are more than 20 wheel set parameters that need to be detected, such as wheel flange thickness, rim width, wheel set tread scratches, local concave depth and peeling length, etc. These are important para...
